I've been preparing Blue Jund for a post-Lavinia metagame; namely one that revolves around the successful resolution of the creature (either through FoWing it through or perhaps via Cavern).

Blue jund was a logical consideration due partly to its non-reliance on FoW and a heavy non-xerox manabase.

However, with a decline in Oath observable in the meta with a steady increase in Paradoxical Outcome; the life-total within any given 'blue' based matchup has altered.

To qualify my statement relating to the my expectation of the post-Lavinia meta might rotate around a bifocal axis a) decks that utilise her to disrupt the opponent to assemble their own combo (Paradox) b) decks that utilise her to hate out a combo (Xerox, Humans). The third way is perhaps to assemble as to not be affected by her non-symetrical effect to the same degree.

Partially in celebration of @Brass-Man (currently at the time of writing) playing Death's Shadow in the VSL, I have reconfigured the deck as to capitalise on the life-loss which Sylvan Library/Thoughtseize had exacerbated in the decks previous iteration. Further to this, I have observed a reduction in StP in the meta, replaced by sweepers and lightning bolts. Thus the channelfireball legacy tech of Reanimate seems like an interesting possibility. Reanimating a Vengevine, Grave Troll or such like seems quite powerful on a secondary axis.

Lastly, Lavinia itself seems to punish a) heavy moxen decks, b) FoW/MindbreakT/Misstep decks, c) delve decks; and Blue Jund simply does not play those (4x misstep, but they are almost exclusively for removal).

to not leave it too open, and imprecise, the SB is perhaps the most important aspect of the most important games in magic. The games that can make you lose a match. No one can lose a match game one, that's a fact.

Thus, a common held concept is that you must, in the instance you are not one of the two categories described henceforth, segregate 6 or so cards to beat workshop and bazaar type decks. you 'must' be able to beat workshop if you play workshop, and so on.

My mission is not to run through then minutia of all the specificities of each deck interacting with one another; rather a sober voice, to explicitly say exactly how they interact with any other deck.

The concept derives from @Smmenen talking about his approach to beating PO via Jeskai (via podcast i believe). His summary was, and hopefully is, not to beat PO via stony silence/null rod, but perhaps attacking the artifacts 'on the field'. Thus his SB features Fragmentise rather than SSilence.

The way that I look at this card is through a rubric similar to Mystic Remora, that is to say that in a mirror matchup the player that plays this card first is vastly advantaged. Therefore a turn one play of this is much more powerful than subsequent turns.

Paradoxical Outcome decks will undeniably be able to cast this on turn 1 via:

@nower1990 If white Eldrazi is specifically causing you concern, I would suggest taking a look at Goblin Cratermaker. It doesnt get taxed by Thalia/Thorn, can shoot all the white Eldrazi's white creatures or destroy the colorless fatties and Thorn/Chalice. Lastly the card is also quite splash-able due to the 1R casting cost and 1 generic activation cost.

the general theory posits that you either play discard spells or counter spells. it seems that cabal therapy is a prerequisite. Thus mana drain, the quintessential counterspell seems counter intuitive.

also, from my testing the difficulty arises in sacrificing rector; not casting it
